Patent CA-2019133-A1 (CA)
IPC: H04N1/411
Filed: 1990-06-15
Abstract: The invention relates to a method for the compression and decompression  of  binary  text  images.   The  method distinguishes between large low-frequency areas and small high-frequency  areas  in  the  original  frame.  For  the low-frequency areas,  a scheme for lossy compression is used,  whereas for the high-frequency areas,  a  scheme permitting   lossless   compression   is   applied.   The compression/ decompression process involves the following five  stages  -  (1)  prefiltering  to  remove  all  black patches (e.g. by removing all black pixels, except where they belong to a large black segment; (2) fast evaluation of  compressibility  by  partitioning  the  images  into mutually  exclusive  segments  and  applying  different compression  modes  to  each  segment;  (3)  connectivity oriented  subsampling  to  reduce  the  resolution  in horizontal  and  vertical  directions  (the  image  is segmented into blocks, and a 1-pixel representation for each block is determined);  (4) lossless compression and decompression where the reduced file is compressed by conventional  techniques;  and  (5)  reconstruction  by sequence reversal (lossless decompression will retrieve the subsampled file,  expansion of the subsampled file through replacement of each pixel by a block having equal value, postfiltering).

Abstract: Abstract The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a permeable mass of filler material or a preform with molten matrix metal and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body and/or a metal or metal containing body. Particularly, an infiltration enhancer and/or infiltration enhancer precursor and/or infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform.  Moreover, prior to infiltration, the filler material or preform is placed into contact with at least a portion of a second material such that after infiltration of the filler material or preform, the infiltrated material is bonded to the second material, thereby forming a macrocomposite body.

Abstract: A gas nozzle has a body threaded on a threaded conduit with an insert therebetween. This insert is not changed for another insert in order to adapt the nozzle to either natural gas or LP gas; instead, the body is tightened onto the insert and threaded conduit for LP gas and is loosened about one thread for natural gas. The insert has a first restricted orifice and a bypass passageway around this restricted orifice. The body has a second restricted orifice which is larger than that of the first restricted orifice. Thus, When the body is tightened on the conduit, a seal is made to close off the bypass passageway and the gas flow is through the first and second restricted orifices in series. When the body is loosened, the bypass passageway comes into effect and the gas flow is also through the bypass passageway to be restricted only by the second restricted orifice. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: A tamper resistant container is provided, which comprises a complimentary lid and a base formed from resiliently deformable plastic.  Together, these are releasably resealable when respective wall portions thereof are secured in frictionally internested relation.  Opposed, axially spaced apart circumferential grooves and beads are thereby arranged in interfitting register to resist unauthorized axial withdrawal of the lid from the base.  Such leverage as might be applied to an outermost one of these base walls in order to expose protected undersurface potions of the lid, (and apply the axial leverage needed to separate the lid from the base), biases the internested grooves and beads into securely seated relation.  If further leverage is applied to the outermost wall the necessary forces exceed the resistance of an intermediately frangible zone of weakness (extending along a portion of the outermost wall and the base), to tearing.  This results in visible evidence of tampering.          Authorized access, on the other hand, is facilitated by a readily frangible tab portion arranged between lines of weakness in the outermost wall.

Abstract: A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. Macroinstruction pipelining is employed (instead of microinstruction pipelining), with queueing between units of the CPU to allow flexibility in instruction execution times.  A wide bandwidth is available for memory access; fetching 64-bit data blocks on each cycle.  A hierarchical cache arrangement has an improved method of cache set selection, increasing the likelihood of a cache hit.  A writeback cache is used (instead of writethrough) and writeback is allowed to proceed even though other accesses are suppressed due to queues being full.  A branch prediction method employs a branch history table which records the taken vs. not-taken history of branch opcodes recently used, and uses an empirical algorithm to predict which way the next occurrence of this branch will go, based upon the history table.  A floating point processor function is integrated on-chip, with enhanced speed due to a bypass technique; a trial mini-rounding is done on low-order bits of the result, and if correct, the last stage of the floating point processor can be bypassed, saving one cycle of latency.  For CAL type instructions, a method for determining which registers need to be saved is executed in a minimum number of cycles, examining groups of register mask bits at one time.  Internal processor registers are accessed with short (byte width) addresses instead of full physical addresses as used for memory and I/O references, but off-chip processor registers are memory-mapped and accessed by the same busses using the same controls as the memory and I/O.  If a non-recoverable error detected by ECC circuits in the cache, an error transition mode is entered wherein the cache operates under limited access rules, allowing a maximum of access by the system for data blocks owned by the cache, but yet minimizing changes to the cache data so that diagnostics may be run. Separate queues are provided for the return data from memory and cache invalidates, yet the order or bus transactions is maintained by a pointer arrangement.  The bus protocol used by the CPU to communicate with the system bus is of the pended type, with transactions on the bus identified by an ID field specifying the originator, and arbitration for bus grant goes one simultaneously with address/data transactions on the bus.
